Cutting to the chase, it requires approximately 55 times more energy to get to the Sun (from the Earth) than it takes to get to Mars!
- PaulHoule 6y ago"Energy" is the wrong unit. In astronautics you would measure the difficulty of the mission with Δv, not energy. If you only had to deal with energy conservation, space travel would be easy. You have to deal with momentum conversation too, carry your own reaction mass, etc.
